A user station for a serial bus system. The user station includes a communication control device for controlling a communication of the user station with at least one other user station, and a transceiver device to serially transmit a transmission signal generated by the communication control device onto a bus and to serially receive signals from the bus. The communication control device generates the transmission signal according to a frame, and inserts a header check sum into the frame, only bits of a frame header that is situated in front of a data field provided for useful data in the frame being included in the computation. For computing the header check sum, the communication control device uses a predetermined starting value and a predetermined check sum polynomial.

An information security protection method includes: repeatedly substituting a plaintext into an encryption algorithm to obtain a plurality of ciphertexts, and. determining whether the ciphertexts are all the same h the processor core. Each time the processor core substitutes the plaintext into the encryption algorithm, the encryption algorithm outputs a ciphertext. When the processor core determines that the ciphertexts are not all the same, the processor core outputs a hacker attack message, which means that an encryption process has suffered a hacker attack.

A method for providing and maintaining secure storage of target data includes, during a first time period in which a server provides a first mapping between user-specific cloaking sequence elements and hidden sequence elements, cloaking the target data using a first set of user-specific cloaking sequences and the first mapping, and storing the cloaked data in a persistent memory. The method further includes, during a later, second time period in which the server provides a different, second mapping between the user-specific cloaking sequence elements and the hidden sequence elements, re-cloaking the cloaked data using the first set of user-specific cloaking sequences and the second mapping, and storing the re-cloaked data in the persistent memory.

A secure inference over Deep Neural Networks (DNNs) using secure two-party computation to perform privacy-preserving machine learning. The secure inference uses a particular type of comparison that can be used as a building block for various layers in the DNN including, for example, ReLU activations and divisions. The comparison securely computes a Boolean share of a bit representing whether input value x is less than input value y, where x is held by a user of the DNN, and where y is held by a provider of the DNN. Each party computing system parses their input into leaf strings of multiple bits. This is much more efficient than if the leaf strings were individual bits. Accordingly, the secure inference described herein is more readily adapted for using in complex DNNs.
